Transmucosal glucagon rapidly increases blood glucose concentration in healthy cats.

Objectives: To evaluate the effect of transmucosal glucagon powder (Baqsimi; Amphastar Pharmaceuticals) on blood glucose (BG) concentrations in healthy cats and describe adverse reactions to its administration.

Methods: A randomized, controlled, crossover study was conducted on six healthy cats with a 7-day washout period between treatments. Transmucosal glucagon powder was administered intranasally and rectally and compared with intranasal placebo.

Next steps for targeted protein degradation.

Targeted protein degradation (TPD) has greatly advanced as a therapeutic strategy in the past two decades, and we are on the cusp of rationally designed protein degraders reaching clinical approval. Offering pharmacological advantages relative to occupancy-driven protein inhibition, chemical methods for regulating biomolecular proximity have provided opportunities to tackle disease-related targets that were undruggable. Despite the pre-clinical success of designed degraders and existence of clinical therapies that serendipitously utilize TPD, expansion of the TPD toolbox is necessary to identify and characterize the next generation of molecular degraders.

An atypical E3 ligase safeguards the ribosome during nutrient stress.

Metabolic stress must be effectively mitigated for the survival of cells and organisms. Ribosomes have emerged as signaling hubs that sense metabolic perturbations and coordinate responses that either restore homeostasis or trigger cell death. As yet, the mechanisms governing these cell fate decisions are not well understood.

Development of Ligands and Degraders Targeting MAGE-A3.

Type I melanoma antigen (MAGE) family members are detected in numerous tumor types, and expression is correlated with poor prognosis, high tumor grade, and increased metastasis. Type I MAGE proteins are typically restricted to reproductive tissues, but expression can recur during tumorigenesis. Several biochemical functions have been elucidated for them, and notably, MAGEs regulate proteostasis by serving as substrate recognition modules for E3 ligase complexes.

Assessing ventilation through ambient carbon dioxide concentrations across multiple healthcare levels in Ghana.

Infection prevention and control (IPC) measures safeguard primary healthcare systems, especially as the infectious disease landscape evolves due to climate and environmental change, increased global mobility, and vaccine hesitancy and inequity, which can introduce unexpected pathogens. This study explores the importance of an "always-on," low-cost IPC approach, focusing on the role of natural ventilation in health facilities, particularly in low-resource settings. Ambient carbon dioxide (CO2) levels are increasingly used as a measure of ventilation effectiveness allowing for spot checks and targeted ventilation improvements.
